A SENIOR aide to Human Resources Administration chief Verna Eggleston is a chiropractor who’s being allowed to keep her practice while working for the city full-time.

Lisa Bostroem, a $119,595-a-year special adviser to the commissioner on “health and wellness,” told The Post she puts in a full week on her city job and works as a chiropractor in Brooklyn on Thursday nights and Saturdays.

“I work a regular 40-hour week,” she said of her city position.

Bob McHugh, HRA’s spokesman, said the Conflicts of Interest Board approved the arrangement in a ruling on Feb. 26, 2003.

When a reporter called to make an appointment and asked if Bostroem performed all the procedures, a secretary replied: “She comes. She does the treatments. She’s the doctor. Why are you asking?”

But Bostroem said another chiropractor, Marie Pehush, handles all the appointments except on Thursdays and Saturdays.

Bostroem, who leaves HRA in lower Manhattan at 4:30 on Thursdays, says she comes in early to make up the half-hour.

McHugh said the job, which was created for Bostroem, consists mainly of research and analysis aimed at finding jobs for hard-to-place welfare recipients. He described the position as “unique.”

Bostroem holds a master’s degreee in public health from Columbia.

About 40,000 property owners and their representatives got quite a jolt recently when letters arrived from the Tax Commission stating that their properties were worth far more than what was on the assessment roll.

“There was a mistake made in using an old [computer] tape,” explained Tax Commission president Glenn Newman.

He said corrective letters are being mailed, with the right numbers. Oops.

The proposed West Side football stadium is grabbing daily headlines, the Yankees will soon be in the spotlight when they unveil plans for a new ballpark in The Bronx – but the Mets haven’t said a word in months about a new Shea Stadium.

Queens Borough President Helen Marshall said that’s because they can’t pay for a $700 million to $800 million stadium, as Yankees boss George Steinbrenner is preparing to do.

“They don’t have the capital,” Marshall said of the Mets.

The Mets have insisted they have to get whatever the Yankees get. But right now it looks like the Mets face a shutout.
